Presented here are the results concerning a hydrogen sensor based on a novel bilayer structure with lead and cobalt phthalocyanines in a Surface Acoustic Wave dual-delay line and electric systems. The sensor material consists of two layers produced in two different vapour deposition processes. The first one is a lead or cobalt phthalocyanine (~310nm PbPc or 200nm CoPc) layer, whereas the second...

We report the reaction dynamics of cobalt phthalocyanine (CoPc) molecules with Bi-line structures (BLSs) on a Si(100) surface, investigated using scanning tunneling microscopy (STM). When CoPc molecules were deposited on a Si(100) surface with BLSs at room temperature, single-spot protrusions were observed in the STM image instead of four-spot images corresponding to CoPc’s flat molecular struc...
